Register 7: GPIO Raw Interrupt Status (GPIORIS), offset 0x414
The GPIORIS register is the raw interrupt status register. A bit in this register is set when an interrupt
condition occurs on the corresponding GPIO pin or if a µDMA done interrupt occurs. If the
corresponding bit in the GPIO Interrupt Mask (GPIOIM) register (see page 764) is set, the interrupt
is sent to the interrupt controller. Bits read as zero indicate that corresponding input pins have not
initiated an interrupt. For a GPIO level-detect interrupt, the interrupt signal generating the interrupt
must be held until serviced. Once the input signal deasserts from the interrupt generating logical
sense, the corresponding RIS bit in the GPIORIS register clears. For a GPIO edge-detect interrupt,
the RIS bit in the GPIORIS register is cleared by writing a ‘1’ to the corresponding bit in the GPIO
Interrupt Clear (GPIOICR) register. The corresponding GPIOMIS bit reflects the masked value of
the RIS bit.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
